Abstract

PURPOSE:To improve accuracy and efficiency in working by supplying materials at a point in which the center of a vertical spindle guide movable vertically coincides with that of a material tray movable horizontally to the spindle and enabling two tool rests moved horizontally according to the spindle to be used for a combined fixing and rotating tool. CONSTITUTION:A spindle 1 clamps a material 9 on a work index table 22 and then a pushing pin 33 pushes up a tray 28 while the spindle 1 is raised. Then, the work index table 22 retreats to carry out the same or different cutting operations. And after the competion of cutting work, a tool rest retreats and instead the work index table 22 advances. The spindle 1 clamping the cut material is lowered to fit it in the tray 28. Next, the work index table 22 is rotated so that unworked material is fixedly set. Here, high accuracy working and production efficiency of a variety of workpieces can be improved by interchangeability between a turret tool rest with fixed tool, turret tool rest with rotary tool and combined tool rest.

B. Prior Art Conventional numerically controlled lathes employ a computer-based numerical control system, but loading and unloading materials on the lathe is done manually, which is inefficient. In addition, there are cases in which a Robrad is used for attaching and removing materials, but this requires a large investment, which increases the cost and is rather disadvantageous.

Furthermore, if we look specifically at conventional numerically controlled lathes, the main spindle that grips the material during cutting is mostly horizontal, and Jinren is an example of a manual or robotic method for feeding the material. However, the horizontal spindle requires a large amount of floor space, and manual material feeding has many problems, such as extremely poor efficiency.

In the current state of the prior art, Sagi's invention, which was filed by a non-inventor, combines the headstock mechanism, work index table mechanism, and turret mechanism, makes the functions of each mechanism highly accurate and highly efficient, and improves the inter-mechanism between each mechanism. This system streamlines the cooperative operation of the two systems. The headstock mechanism consists of a vertical headstock and a spindle, and the function of the spindle is to grip the material at its tip.
As a function for this purpose, movement in the direction of the spindle is performed by vertical movement of the headstock, and the spindle can also be rotated. The advantage of this headstock mechanism is that it is vertical, so it takes up less floor space, and the work index table mechanism allows material to be fed from the periphery of a horizontal rotary circular table, instead of the traditional manual or robotic material feeding method. Materials can be placed at regular intervals and rotated appropriately, and can also be reciprocated toward the center line of the spindle of the headstock. With this configuration, when the material placed on the table and the headstock spindle are in the same position, the spindle can grip the material with high precision, and it matches the highly precise movement of the tool post Sakakitaka to achieve high efficiency, high precision, and labor saving. It became possible to perform cutting work.

(1) It consists of three mechanisms: the headstock mechanism, work index table mechanism, and tool post mechanism, and a numerical control mechanism that operates in conjunction with these mechanisms.The headstock mechanism consists of a vertical headstock that can move up and down, and a material at the tip. The work index table mechanism consists of one main shaft with a gripping function, and the work index table mechanism is such that, among the material receiving trays provided at equal intervals around the entire periphery of a rotatable circular table, the material receiving tray facing the main shaft is aligned with the center line of the main shaft. The tool rest mechanism is capable of horizontal reciprocating movement toward the main shaft, and material feeding operation can be performed at the point where its center line coincides with the center of the material receiving tray, and the tool rest mechanism simultaneously performs the same movement in response to the movement of the main shaft. Or it consists of two turrets that operate differently,
Each of the tool rests is capable of horizontal movement toward the center line of the spindle, and can be replaced with either a fixed tool type or a rotating tool type, or a fixed tool and a rotating tool type, and the numerical control mechanism is 1. A vertical numerically controlled lathe with a work index table, characterized in that a work program can be stored and the various mechanisms described above can be operated.

The work index table mechanism consists of a rotatable circular table whose material trays are arranged at equal intervals around the entire periphery, and the material trays facing the main shaft face toward the center line of the spindle. The tool post mechanism is capable of horizontal reciprocating movement and performs a material feeding operation at a point where its center line coincides with the center of the material receiving tray, and the tool post mechanism is capable of simultaneously performing the same or different actions in response to the movement of the main shaft. Each turret can move vertically and horizontally reciprocate toward the center line of the spindle, and can be a fixed tool type or a rotary tool type, or can be used as both a fixed tool and a rotary tool. 1. A vertical numerically controlled lathe with a work index table, characterized in that any of the formulas can be replaced, and the numerically controlled mechanism can store a work program and operate each of the mechanisms.
